The beneficial effects of the utility model:
The utility model uses the barrier layer of FTPV flexible fluorine material as the conveying novel environment-friendly refrigerant hose.FTPV (Fluoro TPV) is a kind of novel flexible fluorine material that is polymerized by ethylene-tetrafluoroethylene copolymer (ETFE) and ternary fluororubber (FKM).This material is a kind of thermoplastic elastic material between fluororesin and fluorine rubber performance, has utmost point hypotonicity for the hydrocarbon that contains in the refrigerant (HC) etc., has the movable needed ductility of material such as bending, distortion simultaneously.Also have excellent resistance to chemical attack and the high low temperature of fire retardant ability, waterproof, low coefficient of friction, good combination properties such as self lubricity.
Thereby the utility model is stronger except that having weatherability, good seal performance, elasticity and ductility are better, in use composite bed be difficult for peeling off come off outside, also have excellent comprehensive performances such as osmotic-pressure-tolerant, high-low temperature resistant, resistance to bending and pulse absorptivity be better, solved the noise and the potential safety problem of thermoplastic material, and improved the ability of anti-refrigerant infiltration and effectively prevent the leakage that refrigerant is connected with flexible pipe at pipe joint.The FTPV flexible fluorine material air-conditioning pipe of a kind of conveying novel environment-friendly refrigerant of the present invention had both satisfied the needs of air conditioning hose to novel environment friendly refrigerant medium, consider the cost of FTPV flexible fluorine material again and guaranteed the body ductility, design multi-layer compound structure for this reason, not only be fit to the long-term operating mode of air conditioner for automobile, its extremely strong anti-tightness, chemical-resistance etc. provide reliable guarantee to the operation of automotive air-conditioning system long-term stability simultaneously, satisfy CO fully
2, dimethyl ether novel environment friendly refrigerant media such as (DME) needs.
